Spec score 7.7 #17 of 35 in Audio Visualizer Software

What it is

projectM is an open-source music visualizer that turns audio input into visuals in real time. Its libprojectM library is intended for application development and reimplements Winamp MilkDrop, including support for user-contributed visualizations. The library analyzes PCM audio with beat detection and FFT, then renders visuals using OpenGL. Preset files define looks through pixel shaders and MilkDrop-style equations, but libprojectM does not include presets. The projectMSDL desktop frontend listens to audio input and produces visuals; standalone options are listed for Windows, macOS, and Linux. The library documentation lists builds for Windows, Linux, macOS, iOS, Android, and WebGL/WASM. The core library is licensed under the GNU Lesser General Public License 2.1. projectM is free and open source. Its available end-user frontends are development previews that may be incomplete or contain bugs, while Android apps linked by the project are not created or supported by projectM developers. Third-party integrations including Kodi, Silverjuke, and VLC are supported by their respective developers, not the projectM team.
